Abstract

In an authentication section 22 of a license server 4, a user using a user terminal 1 is authenticated by using a user ID and a password provided by a user terminal 11 for the purpose of user identification. Then, the user terminal 1 is to be authenticated by using an equipment ID issued by the authentication section 22 for the user ID to specify the user terminal 1. In response when the user ID is authenticated, a content system is allowed for viewing contents in a content server 3, for example. The present invention can be applied to any content system which provides contents to the user terminal. With such a configuration, any unauthorized accesses can be prevented from a plurality of equipment units.

Benefits of technology

[0028] According to the invention, any unauthorized accesses can be prevented from a plurality of equipment units, the copyright protection can be promoted with ease, and information leakage can be successfully prevented.

Problems solved by technology

The issue here is the difficulty of assigning such equipment IDs to the PCs for unit (equipment) identification due to their established standardization.

The problem in this case is that the PC-A is assigned with no ID for unit identification.

Worse still, if the user ID and password of the user A are leaked to the outside by wiretapping or others, his or her user ID and password become accessible with other PCs by malicious third parties.

As such, there has been a problem that the movie content purchased by the user A for viewing becomes available to others.
